Abstract: A current sensing system for sensing current through first and second circuit elements of a circuit in which the first and second circuit elements are active in respective first and second phases of an operational cycle of the circuit, the current sensing system comprising: first current sensing circuitry for sensing a current through the first circuit element; second current sensing circuitry for sensing a current through the second circuit element; and summation circuitry coupled to an output of the first current sensing circuitry and an output of the second current sensing circuitry, wherein the summation circuitry is configured to output a summation signal indicative of a sum of the sensed current through the first circuit element and the sensed current through the second circuit element so as to provide an indication of a total current drawn over an operational cycle of the circuit.
